Distance measuring method based on double lasers

Abstract

The invention provides a distance measuring method based on double lasers. The method comprises the steps that a laser distance measuring instrument is adjusted to be in a horizontal state; the laser distance measuringplate is placed at a first position in front of the laser distance measuring instrument, the distance FB from the first laser distance measuring module to the laser test plate and the distance GC from the second laser distance measuring module to the laser test plate at the first position are obtained, the distance BC is obtained, and the first laser distance measuring module and the second laser test module form a vertex A; the values of AF and AG are solved; the angle value of the angle FAG is solved; then values of AB and AC are obtained; according to the values, the distance AH from the A point to the BC can be obtained; the test distance can be obtained by moving the laser distance measuring instrument to a position needing to be tested; and the collected distance data is more accurate.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a distance measuring method based on dual lasers. Background technique [0002] In the traditional test, the manual measurement method requires more than two testers to measure repeatedly through the tape, and then read and record. The work efficiency is low, the workload of repeated measurement is heavy, it is easy to cause fatigue of the testers, and the subjective factors of the testers are affected Test Results. The single laser ranging method needs to maintain a horizontal state, which is a major operational and personal influence factor. With this method, the test and measurement are convenient, the operation is simple, and the price is low. A single person can complete, measure, record and upload data and other operations. [0003] There is a comparative document CN201720416447, titled: a standing long jump rangefinder based on dual laser rangefinders; this invention ...

Problems solved by technology

[0003] There is a comparative document CN201720416447, titled: a standing long jump rangefinder based on dual laser rangefinders; this invention uses dual laser rangefinders for distance measurement, and this method mainly uses a tripod to place it on the foothold for measurement , because the foothold is on the bunker, it may be uneven, and it cannot be guaranteed to be flat, so that the two emitted lasers are not on the same horizontal plane. By manually rotating the angle value, there is a large error in the angle value, and there is an error in the calculated distance.

The accuracy of the data obtained by this method is not high
